sad to hear that, my potting mix is rather not fix, for those photos I posted, apart from D. Intermediate that I wrap the root with sphagnum moss then potted it fully in black silica sand, I use sphagnum moss for the rest...

For photographing time, the last photo was taken roughly at 2pm(you see part of the tray is shadowed by me), while the rest are taken roughly at evening 6pm(when I took photo of D. Adelae was still bright, then dark cloud makes the setting darker soon and I forgot to switch on the flash light of my phone cam...)
